Answer:

∠STU = 40°

Step-by-step explanation:

Using the properties of the rhombus

• The diagonals bisect the angles

• Consecutive angles are supplementary

Sinc the diagonals bisect the angles then

∠UST = ∠USR = 70°, hence

∠RST = 70 ° + 70° = 140°

Hence ∠STU = 180° - 140° = 40° ( consecutive angles are supplementary )

Do 70°, 90°, 20° make a triangle and what kind
vovangra [49]
Yup. The angles of a triangle must add up to 180°—no more, no less.

These angles do: 70+90+20=160+20=180

As for which kind, we can classify it based on the 90°-angle. Since that's a right angle, we have a right triangle. Additionally, it is scalene.

What is an equation of a line passing through the given point
Mademuasel [1]
I believe it is y=mx+b..........y equals slope times x plus the y intercept...or y=-8/3x+4.that would mean your slope would be negative. meaning it would go from the left top hand corner and fall through to the bottom right hand corner.
